First lets say the obvious. This isn't going to make your hammer drill into a jack hammer. But, if you have modest expectations and need to chip off a few tiles or even a smooth a small (really small) section of concrete, this will do the trick.
I worked extremely well in removing the titles around my tub. It is my first SDS tool, and it was helpful that you rotate it for the best possible position when getting into corners.
I removed tile in an entire bathroom, including the floor this. The chisel looks slightly dulled but I think it could last through another demo. I will buy again.
Great chisel for my Milwaukee rotary hammer.. perfect for cleaning up the edges to a nice square so you can throw an expansion joint in before you pour..
